Answer:
The program in Python is as follows:
text_input = input("Enter text: ")
first_word = text_input.split(" ") 
new_text = text_input.replace(first_word[0], "") 
new_text = new_text + " "+ first_word[0] 
print("New Text: " + new_text)
Step-by-step explanation:
This line gets a line of text from the user
text_input = input("Enter text: ")
This line splits the text into list
first_word = text_input.split(" ") 
This line deletes the first word of the string
new_text = text_input.replace(first_word[0], "") 
This line appends the first word to the end of the string
new_text = new_text + " "+ first_word[0] 
This line prints the new text
print("New Text: " + new_text)
